is 2ff a typo ?
lspci has been supporting them since commit 144b0911cc0b ("ls-ecaps:
extend decode support for more fields for AER CE and UE status"):

Amend the AER driver to recognize them as well, instead of logging them as
"Unknown Error Bit".

Last amendment of aer_uncorrectable_error_string[] was in 2019 for an
error introduced in PCIe r3.1, see commit 6458b438ebc1 ("PCI/AER: Add
PoisonTLPBlocked to Uncorrectable error counters").
